K2 focusing screen pulled from a Nikon FM2N and appears to be in good condition. My research show this is the K2 type screen which will fit the FE2, FM2n, FM2T, FA, FM10 and FE10 models. Type K2/B2/E2 screens have a notched tab. This appears to be the K2 screen!!
NOTE: If you use the Type K/B/E screen, you must make exposure compensation by setting the exposure compensation dial to -1/3. However, no exposure compensation is necessary when performing TTL auto flash photography with a Type K/B/E screen installed in the FE2 or FA.
